If you are seeking a FPS for mobile, "Flats" is the game for you. The multiplayer is well synchronized, and there are multiple single player modes such as zombie survival and deathmatch. Players are able to carry two weapons, and they have to choose between rifles, shotguns, pistols, snipers, SMGs, grenade launchers and light machine guns. Dropped weapons can be swapped with currently equipped weapons should ammo run out.

In game, players are able to jump, sprint, aim down sights and throw grenades. Moving is done via the half of the screen, and aiming is done by swiping the other half. Firing and other actions are done via either tapping or holding the buttons. Each button can be modified in size and location via the options menu, and the dominant playing hand can also be changed.

While there is no story, Flats focuses on the purity of FPS, and in that it succeeds in bringing the fun of FPS to mobile.
